SSH ETS 300 639:1996 ed.1

Transmission and Multiplexing (TM); Sub-STM1 Digital Radio Relay Systems (DRRS) operating in the 13 GHz, 15 GHz and 18 GHz frequency bands with about 28 MHz co-polar and 14 MHz cross-polar channel spacing

Scope

This European Telecommunication Standard (ETS) specifies the minimum performance parameters for terrestrial fixed services radio communications equipment, as given below, for operation in the 13 GHz, 15 GHz and 18 GHz frequency bands (i.e. 12,75 to 13,25 GHz, 14,50 to 15,35 GHz and 17,70 to 19,70 GHz). The equipments covered by this ETS are intended for operation with about 28 MHz basic channel spacing with frequency re-use either in 14 MHz interleaved mode or in co-channel mode (definitions are in ITU-R Recommendation F.746 [27]).
